The specific embodiment
Extremely shown in Figure 6 such as Fig. 2, embodiment for solar energy crystal silicon cell screen printing scraper of the present invention, it comprises printing cutter main body 1, described printing cutter bottom part body is equipped with printing cutter scraping article 13, described printing cutter main body 1 left and right sides hangs respectively the feed back wing of fixing a circular arc, and feed back wing bottom is equipped with feed back wing scraping article 23.
Bottom, the described printing cutter main body back side is provided with a cascaded surface that descends, fix a printing cutter time body 10 on the cascaded surface, printing cutter main body 1 and 10 of printing cutter time bodies form a printing cutter scraping article mounting groove 14, described printing cutter scraping article 13 is installed in the printing cutter scraping article mounting groove, is integrated by screw fastening between described printing cutter main body and printing cutter time body.Described printing cutter scraping article 13 is square column, and described printing cutter scraping article mounting groove 14 is the square groove of unfilled corner, and one jiao of unfilled corner from printing cutter scraping article mounting groove of printing cutter scraping article is stretched out.
The described feed back wing is comprised of feed back wing main body 2 and feed back wing accessory body 20, feed back wing main body 2 hangs and is fixed in printing cutter main body 1 sidepiece front, feed back wing accessory body 20 is fixed in feed back wing main body 2 back sides, feed back wing main body 2 and 20 formation feed backs of feed back wing accessory body wing scraping article mounting groove 24, feed back wing scraping article 23 is installed in the feed back wing scraping article mounting groove 24.Described feed back wing scraping article 23 is cylindrical structure, and described feed back wing scraping article 23 mounting grooves are that excircle is established cylinder groove jaggy, and the outer circumference surface of feed back wing scraping article is outstanding from the breach of feed back wing scraping article mounting groove.
Described feed back wing main body 2 one sides are provided with projection 21, described projection by screw fastening on printing cutter main body 1, upper end, described printing cutter main body 1 side is provided with chimb 11, described chimb front is provided with a table top 12 that descends, described table top is concordant with printing cutter main body 1 side, and described projection 21 upper ends are fixed on the table top.Described projection is provided with a fastener hole 22 that supplies screw to pass, and described fastener hole is oval.Perhaps described fastener hole is vertical strip structure.Can move up and down with respect to printing cutter main body 1 by these fastener hole 22 feed back wing main bodys 2, after being adjusted to correct position, pass through screw fastening.But described fastener hole 22 make feed back wing main body 2 up-down adjustment+0.38mm ,-1.00mm.The thickness of described feed back wing main body and feed back wing accessory body equates and equals to print half of cutter body thickness.Described projection exist feed back wing main body 2 roughly L-shaped, the height of projection 21 is 1/3rd of printing cutter main body 1 height, described feed back wing bottom part body Partial Height equals feed back wing accessory body height.
Described printing cutter scraping article 13 and feed back wing scraping article 23 are silica gel structure, and the length of side of described printing cutter scraping article is 9.8mm, and the diameter of described feed back wing scraping article is 9.8mm.The length of described printing cutter main body 1 is 160mm, the length 〉=20mm of the described feed back wing, and the angle of described feed back wing circular arc is 50 degree.
Analyze by the structure to former printing scraper, the entire length of former printing scraper by 180mm, is revised as the long 160mm of printing cutter main body, the while is respectively designed a circular arc feed back wing that exactly likes ox horn in the both sides of printing scraper.Like this can with the printing area of coverage of former printed strip 180mm, be reduced to the printing overlay area of 160mm.Now the main specifications of solar energy silicon wafer battery is 125,156 at present, and the slot pitch successor who revises the printing cutter so can satisfy the printing of solar energy silicon wafer battery.After the entire length of printing cutter was revised, former printing scraping article was that 180*9.8*9.8 need to change to the use that 160*9.8*9.8 cooperates the printing cutter with the printing scraping article.The mounting means of the printing scraping article mounting groove of printing scraper adopts the snap close mode, by four fastening clamping printed strip of M4*25 soket head cap screw.
For realizing the feed back function of printing scraper, respectively design a circular arc feed back wing that exactly likes ox horn in the both sides of printing scraper.Feed back wing bottom design is installed the feed back wing scraping article of arc silica gel strip structure, and feed back wing scraping article and printing cutter scraping article position and same level face can be avoided half tone and Metal Contact, and silica gel contacts with half tone and effectively protects half tone injury-free during work.The mounting means of the feed back wing is side mounting, and feed back wing main body is installed with printing cutter main body by the fastener hole of design.
Feed back wing main body and the installation method that prints the cutter main body adopt the M4*20 soket head cap screw that the feed back wing main body of the feed back wing is fastened on the printing scraper both sides, and be easy for installation.But feed back wing up-down adjustment+0.38mm ,-1.00mm, but suitable like this thrust Effective Raise feed back effect.Both sides install that the shape of whole printing scraper is the ox horn shape behind the feed back wing, so just with the right angle of former printing scraper, have changed arc chord angle into.The printing scraper of arc chord angle, with returning blade every Ullage from becoming arc chord angle every sky by parallel every space-variant.Former parallel every Ullage by 10mm, be arc chord angle after the change every Ullage from being 1.26mm, every Ullage from greatly reducing.The arc chord angle of printing scraper and the arc chord angle of returning blade block before and after just forming, and slurry can be remained between printing scraper and the returning blade motion that moves in circles in the process of front and back extruding like this.Thereby realize the feed back function of printing scraper, solve former right angle printing scraper the slurry problem of piling up, the corresponding relevant issues that cause because of accumulation that just solved of the accumulation problem that has solved slurry.
